There are a lot of problems with the current materials that dentists use for cavity fillings, crowns and other dental implants.  For example, they fall out. Normal everyday things like chewing and eating hard or acidic foods can wear down a filling and its bonding with the surrounding tooth. And this can lead to the filling cracking or falling out. God forbid you chew... with your teeth!

And the problem of the falling-out fillings could be solved by mussels! Well, not actually mussels, but the adhesive they use to stick to things. For years, scientists have been searching for a strong, reliable, adhesive. And now, inspired by nature, they think they've found it.

These little creatures have an incredible ability to tightly stick to wet surfaces like rocks and boats and hang on for dear life. And because of this bonding, they can withstand a lot - pummeling waves, blistering, dry heat, and salt water cycles. They do this with what are called byssal threads.
